Application filed August 28, 924; Serial No. 734,660.

The invention relates to corn sheller attachments, and has for itsobject to provide means for eliminating noise, loss of time and expenseof removing shelled corn from the baffie board upon which the shelledcorn falls, when removed from the cob by the shelling mechanism of thecorn sheller. It has been found that under favorable conditions the cornwill slide downwardly on the conventional form of baffle board, which isstationary, but when the corn is damp it,

accumulates on the baffle board, preventing further operation of thesheller, until the lodged corn is removed. It has also been found thatdirt or other foreign matter intermixed with the shelled corn will lodgethe same as damp corn, therefore it is an object of the invention toprovide an inclined baffle board, hingedly mounted and hingedlyconnected to the reciprocating separator box, which bafile board willoscillate and dislodge. the corn therefrom.

A further object is to provide a connecting rod for the separator boxcomprising spaced arms, which arms terminate in a transversely disposedelongated, separable bearing connected to the crank of the crank shaft,thereby materially strengthening the bearing and connecting rod andobviating the difliculty found in connecting rods as at present used.

With the above and other objects in view the invention resides in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawing, described and claimed, it being understood that changes inthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is alongitudinal sectional view through aportion of a conventional form of corn sheller showing the baffle boardapplied thereto.

Figure 2 is a perspective view of a portion of the shaker box and theconnecting rod.

Figure 3 is a perspective view of a por tion of the separator box andthe bafiie board.

Referring to the drawing, the numeral 1 designates a conventional formof corn shelling machine and 2 the shelling mechanism thereof. The corn,as it is shelled, drops onto the baflie board 3, and shaker box 4- inthe usual manner. However it has been found that where the battle boardis stationary that damp corn or dirt collects thereon incident to theshaking operation, and it is necessary to dislodge the same therefromfrom time to time. To obviate this ditliculty the battle board 3 ishingedly mounted at 5, and extends downwardly and is hingedly connectedat 6 to an upwardly extending plate 7 carried by the end 8 of theseparator box. Therefore it will be seen that the batiie'board 3 willoscillate during the oscillation of the separator box. The separator box4 is guided in its movement in the usual manner by means of members 9carried thereby which are disposed in slots 10 in the sides of the cornsheller, therefore it i will be seen that an elongated bearingconnection 11 is necessary between the plate 7 and the lower'end of thebaflle board so that the shaker box will not be held against movement bythe. bafile board.

Extending transversely of the sheller 1- is thecrank shaft 12 of aconventional form, which crank shaft is provided with a crank 13, onwhich is mounted a relatively long transverse bearing 13*,preferablyseparable as shown, and which bearing 13 is provided withupwardly inclined integral parallel arms 14:, which are connected to thetransverse rod 15 carried by the separator box. It has been found thatthe uneven forward and backward movement of the connecting rods ofconventional forms of shellers soon wear the short box bearings carriedthereby, anl cause loss of time and expense incident to repair andupkeep. By providing the a single elongated bearing and the arms 14-carried thereby, two independent bearing members are obviated,consequently the bearing will evenly wear and the alinement thereof willbe maintained, which is not the case where two bearing members are used.

From the above 1t Wlll be seen that a movable baffle board is providedfor corn shellers, which will prevent the lodgement of corn and dirtthereon, consequently will obviate the stopping of the machine from timeto time to remove the corn and dirt from the baffle board. It will alsobe seen that a single bearing member relatively long is provided forseparator box which will obviate the common difficulties incident tomisalinement of two separate bearing members and rapid Wearing thereof.

The invention having been set forth What is claimed as new and useful isThe combination with a corn sheller, a separator box, means forreciprocating the separator box, of 'a downwardly inclined bafiie board,said bafiie board havingits upper end hingedly n10iinte'd, an upwardlyextending rigid flange carried by the separator box, a hinge connectionbetween the lower end of the bafile board and the upwardly extendingflange of the separator box, said last named hinge connection being aloose one whereby said flange of the separator box may move with themovement of the separator box and the bafiie board may arouately swingduring the movement of the separator box.

In testimony whereof I afiix my signature.
